Abstract: The traditional fault diagnosis methods that depended on human being or signal analysis were difficult to deal with the increasingly complicated intelligent aircraft electrical systems. The development of artificial intelligence and software technology made it possible to solve this problem. In accordance with the principles of model-based fault diagnosis and using RODON fault diagnosis software, a simulation model of aircraft generator system was built. Failure analysis of aircraft generator system was used to verify the usefulness and efficiency of model-based fault diagnosis method.
